.lle it known that l, AUGUST C. l-IAGHFIELD, eeitizen of the United States, residing et itlilwoukee, county of llililwouliee, sind Siete of Wisconsin, have invented new and useful improvements in slLBesrings, of which the toller-ring is s specification.

lily invention relates to improvements in lia-likjeenrings.A

liellbosriugs lieve heretofore been generally regarded as available only for light loods, es the amount of leed to be eorried by one si olE bells 'is neeessorilylimited, and the use oit "more thon two sets of balls in o single, hearing hes heretofore been regarded es iu1- prooi-.irish (uving to the foot that slight verintions in either the bells or their reces are in i-"orinblyfound to exist either 'in the bearing es originally constructed or alter a. period of use. l/fhere such variations exist in any or dinnry Form ol bearing, the load tlu'mvn upon the two bells or sets of bulls Whieh ure rel th of the beerine' is therefore limited to l D e tenacity of two sets of balls to sustain it.

,lhe object of this invention is to provide a 'form or structure in which n'single hearing' nifty be termed with a. plurality of ball-re uw esili. set arranged to receive itsportion of the leed between the planes of the sets of bells pertsining thereto, that portion ol' the sleev5e Whioh is eoneentrie With the balls being free to yield suliieiently to cause o distribution oli the lood to the bells oli both sets. ln designing suoli e beerinff l have also aimed to pro- "ide s structure lniilinghut few ports and eliieh requires e. minimum zunount or nin.-

' ahineforli and labor in assembling the parts sund 1" wiiieh eooh of sleeves and theirt .med bells may lio-removed end replaced {zOli i en .individuel unit.

l is the axle-shaft of o vehicle, :ind 2 is e. bearing-box, which in this cose also eonstitutes the wheel-hub, e portion of the spokes 3 being also shown. l

4l is on outer end esp, and 5 is e dust-excluding nut screwed. tothe inner end of the sleeve and covering e series of annuler ribsor dust-exeluding llonges 6 on the axle-shaft.

The inner surfer-.e of the box 2 is provided with 'annule-r shoulders 8, preferably rounded i eoneovely, es shown, end erich adopted to receive o rndiolly-extending convex s ioulder Sl on the bellinelosing bearing-sleeve 10. The outer surface of the sleeve l0 is so formed that ell portions thereo]c except the f shoulder 9 are out of Contact with the box;

und es the shoulder 9 is located substantially et the center of the sleeve it is obvious that the sleeve is permitted. to rook or tilt longitudinally within the' box 2. The interior wells of the sleeves ere preferably smoothsurloeed :ind arranged to converge eonieally toward the Center of the box 2.

.The interior sleeve l2 of tlui inner set is l formed to lit e eoneevely-rodhtled shoulder 13, against which it abuts when in osition. This sleeve is provided with two all-rece channels 14 and 15, respectively, which ore preferably tl-shaped in cross-section und en ranged for e two-point Contact with'the balls l l. The interior sleeve 16 of the outer set is located upon e reduced end 'portion ol the axle-shoft beyond thoshoulder l?, the shnft being' sorexvtlireeded et 1S and provided 'with u nut 19, against Whiehvthe sleeve 16 shuts, es shown. T his sleeve is also provided with boli-receV channels 20 ond 2l, respeotively7 which 'ore similar in iorin to the channels 14 end 15. The ohsnnels 14- end l5, 20 end 2l ere located neer the ends of the i sleeves, respectively, sind the bells therefore Contact with the inelosing sleeves 10 on oppo site sides of the plane of the shoulder 9 in esl-eh ease. As the ends of the sleeves 10 in the plnnes of the balls are out of oonteot'with the inolosing box, they :tre permitted to tilt slightly,l end thus distribute the leed to both sets ol bells, notwithstanding slight variations in their size or in the roces, which wouldv otherwise throw the entire strain upon the The materiel of which the sleeves 10 are composed will also be per .Initted to; yield slightly if the pressure becomes excessive at any one point in the bearingJ thus relieving the pressure upon the bell at that', point. are imlirem'milig rings 'fitted to suitable channel@ iii iii" ailinciossleeves i() fit their exterior omis, and 26 is zi, nut Scrawci uponih dnd 0i Elio audi if@ will be oiiserraii; Limi the sieeveii i2 imi i@ firs- 'laaper'ed togiii ich@ renier of the box in correspomiemiifilih the tapering; or Conioiil interior Suiies of the outer' sleeves 10.
